Symmetry-protected topological phases of alkaline-earth cold fermionic atoms in one dimension
H. Nonne, M. Moliner, S. Capponi +2
We investigate the existence of symmetry-protected topological phases in one-dimensional alkaline-earth cold fermionic atoms with general half-integer nuclear spin I at half fillin…
Combined analytical and numerical approach to magnetization plateaux in one-dimensional spin tube antiferromagnets
X. Plat, S. Capponi, P. Pujol
In this paper, we investigate the properties of frustrated three-leg spin tubes under a magnetic field. We concentrate on two kind of geometries for these tubes, one of which is re…
Three-Component Fermi Gas in a one-dimensional Optical Lattice
P. Azaria, S. Capponi, P. Lecheminant
We investigate the effect of the anisotropy between the s-wave scattering lengths of a three-component atomic Fermi gas loaded into a one-dimensional optical lattice. We find four…
Confinement and transverse conductivity in coupled Luttinger liquids
S. Capponi, D. Poilblanc, F. Mila
One--particle interchain hopping in a system of coupled Luttinger liquids is investigated by use of exact diagonalizations techniques. Firstly, the two chains problem of spinless f…
Competing orders in the generalized Hund chain model at half-filling
H. Nonne, E. Boulat, S. Capponi +1
By using a combination of several non-perturbative techniques -- a one-dimensional field theoretical approach together with numerical simulations using density matrix renormalizati…
Theory of the Raman spectra of the Shastry-Sutherland antiferromagnet SrCu(BO) doped with nonmagnetic impurities
S. Capponi, D. Poilblanc, F. Mila
Controlled doping of SrCu(BO), a faithful realization of the Heisenberg spin-1/2 antiferromagnet on the Shastry-Sutherland lattice, with non-magnetic impurities generat…
